Another issue that hasn't really been brought up is Peers.
A genius has few peers, least of all themselves. These geniuses you've spoken of have all had amazing concepts, but their actual interaction with the world was less than stellar.
More often than not, those who are brillant in one field or another, have trouble removing themselves from their own head. This causes great problems with their happiness level, because just like anyone else. They want to find friends, love, companionship. If you are to wrapped up in mathmematical equations or strategic movements, or art, or martial arts, or writing. You find that you alienate all people in your life by accident. Not because you do not want them there, but because the lightning crashes against the walls of your skull and you are pulled into your own mind. You write on whatever you can find, walls, floor, your own arm. When you break your reverie, you are alone... By no innate desire of your own.
You find yourself resting in a very snug hermetic cave, placed there by your own obsession and "brillance". In truth, isn't genius just another illness? Another form of psychosis that although breeds amazing and sometimes beautiful creations. Ends up causing chronic misery among those whom bear its laurels?
Thats the lonliness factor, and I think a lot of people have the general right idea. Those who cannot see the mechanics of the governmental/societal machine will usually be "surprised" when good things happen and "Disappointed" when bad things do. But, those are transitory emotions because something "new" will come about soon. To those who can see the gears, they must be able to see what is "coming" before it does. Thus, no good and no bad surprises. In the end, would breed a kind of apathy wouldn't it?
Such a silly little term genius is. Intelligence is the ability to understand the logical movements of our world. Yet, the emotional ripples are the ones that are least understood by those who are supposedly gifted geniuses.
I wonder how many of them, honestly, when approached would've traded their gifts for the ability to be blissfully unaware and happy with the simplicities...
That does raise the question though, can a Genius become enlightened in this lifetime?
If a "Genius" is unable to remove the attachments to their field of study, or shrug off the burden of their own concious mind. Will they ever be able to move past it and allow their thoughts to still?
Maybe that is the source of their unhappiness, somewhere deep in their psyche they know that they will never move beyond the concious mind. That would make me unhappy knowing
Like a splinter in my eye socket. Not being able to see where it was, but definately feeling its burn.
